Engineering graphics educators have been studying students’ modeling strategies and methods of evaluating models for approximately twenty years. Over the last two years studies have been conducted to gain an understanding of students’ engineering graphics literacy by having students read an assembly drawing, visualize the various parts, and then model the parts within a constraint-based modeling program. These studies revealed that the modeling test used was related to other measures of student success in courses – spatial visualization ability, score on the final project, and score on the final exam. Some of the concerns raised through conducting these studies were that the time required to complete the test and the time required to evaluate the models was too long. Recommendations included using a shorter modeling activity, examining a more efficient way of evaluating the models, and conducting qualitative methods for evaluating student modeling strategies.
